v. BALL ROLLER SUPPORTING DEVICE Filed. Oct. 15, 1925 Patented May 27, 1930 QFFEQE HARRY VINCENT BALL, OF CONCORD, MASSACHUSETTS, ASSIGNOR TO B. HOE AND (10., INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK ROLLER-SUPPORTING DEVICE Application filed October 15, 1925.

plicable for use in connection with the shafts of various rollers used in connection with printing presses and similar machinery, some of which are of Very substantial weight and length, so that it becomes desirable to support the same intermediate their ends to prevent sagging.

The obyect of the 1nvent1on is to provide simple, efficient and easily adjustable means for supporting, intermediate their ends, machinery elements such as are above referred to.

The invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as set forth in the claims hereof, one embodiment of the same being illustrated in the accompanying drawings and described in this specification.

In the accompanying drawings,

1 is a fragmentary side view of a portion of an apparatus, as a printing press, showing a roll and one form of my supporting device applied thereto; and

2 is a front view of the same.

Referring to the embodiment of my inven tion which is illustrated in Figs. 1 and 2 of the accompanying drawings, I have there represented a fragment of a machine, as, for instance, printing press, the base thereof being designated 11 and the fragmentary Side frames 10. In the said frames is journaled a shaft 12 upon which is borne a cylinder 13, which may be, for instance, the form-cylinder of a printing press.

Projecting upwardly from the base 11 are members 80, to which are bolted L-shaped supporting members 38. The upper parts of these supporting members are bent into approximately a quarter-circle, as shown in Fig. 3, and supported by the same are rods 40 hearing at their ends rollers 41 (see Fig. 3) which bear against and uphold, intermediate their ends, the shafts 42 and 43, the ends of which are journaled in slots in the side frames 10. A third shaft 44 is also ournaled in slots in the side frames, and is upheld by the L- Serial No. 62,673.

lever 45, which bears upon its inner end a roller 46 and which may be adjusted by the screw 47 (see Fig. The three shafts 42, 43 and 44 bear rollers 48.

The operation and method of use of this embodiment of my invention will be obvious from What has been above said with regard to its construction.

The principal advantage of my invention is that it affords asimple and eflicient means of supporting a heavy roller intermediate its ends in an adjustable manner. The inking rollers of printing presses are of soft and yielding material in themselves, although of very considerable weight, and as the shafts upon which theyare mounted are necessarily comparatively slender, there is sometimes a considerable sag or displacement to the same,

which my invention efiiciently prevents.

ther advantages of the invention will be obvious to those skilled in the art to which it relates.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is as follows: 7

In a printing press, the combination with a supporting frame and an inking, roller journaled therein; of means mounted in said frame and adapted to adjustably support said inking roller, said means comprising a curved arm extending laterally and upwardly from a portion of the main supporting frame, said arm being provided with a plurality of guideways, a rod slidably and adjustably mounted in each of said guideways, each of said rods caring a roller adapted to bear againstsaid inking roller, and means adapted to slide said rods in said guideways.

In witness whereof I have hereunto signed my name this 5th day of October, 1925.

HARRY VINCENT BALL.
